Abstract:
This document gives a summary of the current status for the Gain Calibrations of bcal for Sum-
mer and Fall 2021 Run period. In the detector, the photon shower positions coming from resonant
particle decays are reconstructed using timing information. Since the energy of the photons pro-
duced by π0 decay are determined by the SiPMs attached at the end of the Sci-Fibres, the Gain
Calibration aims to equalize the gains across all SiPM readouts, for values below saturation. A
brief study of optimal corrections and results of incorporating the new Gain Constants is shown
and discussed, as well as the current status of the calibration.
